Joint Learning of Panel VAR models with Low Rank and Sparse Structure
Yuchen Xu, George Michailidis
Panel vector auto-regressive (VAR) models are widely used to capture the dynamics of multivariate time series across different subpopulations, where each subpopulation shares a com…
Dynamic Atomic Column Detection in Transmission Electron Microscopy Videos via Ridge Estimation
Yuchen Xu, Andrew M. Thomas, Peter A. Crozier +1
Ridge detection is a classical tool to extract curvilinear features in image processing. As such, it has great promise in applications to material science problems; specifically, f…
Feature detection and hypothesis testing for extremely noisy nanoparticle images using topological data analysis
Andrew M. Thomas, Peter A. Crozier, Yuchen Xu +1
We propose a flexible algorithm for feature detection and hypothesis testing in images with ultra low signal-to-noise ratio using cubical persistent homology. Our main application…
Testing Simultaneous Diagonalizability
Yuchen Xu, Marie-Christine Düker, David S. Matteson
This paper proposes novel methods to test for simultaneous diagonalization of possibly asymmetric matrices. Motivated by various applications, a two-sample test as well as a genera…
